Title: Production of styrene polymer
Inventor: MATSUBARA TETSUYUKI
IPC: C08F4/00
Filed: 1980-04-21
Abstract: PURPOSE: To continuously produce in high productivity a styrene polymer capable of keeping its high average MW even after molding, by polymerizing a styrene monomer using an organic peroxide catalyst of a specified structure.  
     CONSTITUTION: Continuous bulk polymerization or continuous solution polymerization of a styrene monomer (such as styrene, α-methylstyrene or a mixture thereof with a copolymerizable monomer such as acrylonitrile) or a styrene monomer in which a rubbery polymer such as polybutadiene or a butadiene/styrene copolymer is dissolved, is carried out by using as a catalyst an organic peroxide of the formula, wherein R 1  and R 2  are each H, a C 1W5  alkyl or phenyl. In the polymerization stage, it is possible to obtain a styrene polymer having a high average MW without lowering the yield per unit time, and during molding stage it is possible to prevent MW from lowering. Accordingly, the average MW of the styrene polymer in a molded product is kept high.

Title: Production of phosphorus containing antiirusting pigment
Inventor: AREKUSANDAA MAURAA
IPC: C01B25/32
Filed: 1980-04-21
Abstract: The invention relates to the production of phosphorus-containing anticorrosive pigments with a particle size of at most 20 microns by reacting one or more calcium or magnesium compounds with phosphoric acid or acid alkali metal or ammonium phosphates by intimately mixing an aqueous suspension or solution of the reactants inside a dispersing means rotating at a speed of 3000 to 10,000 rpm. More particularly, fine pulverulent calcium and magnesium compounds are converted, with agitation, together with water and, if desired, a water-soluble alkanol to a homogeneous suspension or solution. The suspension or solution is intimately mixed, inside the dispersing means at 0 DEG  to 40 DEG  C. and in an approximately stoichiometric ratio, with the phosphoric acid or acid phosphate solution. Resulting and precipitated pigment is separated and dried under mild conditions while maintaining its content of water of crystallization. The anticorrosive pigment is comprised of a homogeneous mixture and/or mixed crystals of which 10 to 95 mol % is calcium hydrogen phosphate dihydrate, the balance being magnesium hydrogen phosphate trihydrate. An at least 55 weight % proportion consists of particles with a size of up to 5 microns with a BET-surface of at least 1 m2/g.

Title: Motor drive circuit
Inventor: IZUMI HIKOYUKI
IPC: H02P3/06
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by providing a level regulating means for differentiating the driving voltage being supplied to a motor among respective polarities thereby positioning a motor accurately in a short time. SOLUTION: When a motor 11 is rotated reversely, a control circuit section 21 supplies a current to the relay coil 23a of a relay 23. At that time, a movable terminal 23b is connected to the terminal T3 side and a power supply voltage Vb is supplied to the minus terminal of the motor 11 through a diode D1. Consequently, a corresponding current flows through the motor 11 in the direction from the minus terminal to the plus terminal thereof and the motor 11 is driven reversely. Since the power supply voltage Vb is dropped by the forward voltage of the diode D1, r.p.m. of the motor 11 decreases as compared with forward rotation and the motor 11 can be stopped in a shorter time as compared with a case where the diode D1 is not present. Consequently, the rotational position of the motor can be determined quickly and easily.

Filed: 1986-03-12
Abstract: PURPOSE:To make it possible to carry out a multistage changeover so that 4-position control can be carried out with a device basically the same as that used for three-position control, by stopping the oil burning of one combustion nozzle after the flame of one combustion nozzle which is now ejected to burn is completely shifted to an ejected fuel from another nozzle by the switching of an electromagnetic valve. CONSTITUTION:When a load is increased from a state where oil is ejected to burn using only a low-combustion (30% combustion), a middle combustion electromagnetic valve 2A is fully opened, and a low-combustion electromagnetic valve 1A is fully closed after the passage of a predetermined period of time enough for the positive ignition to a middle combustion nozzle 2, oil being ejected to burn using only the nozzle 2 (70% combustion). Conversely, when the load becomes small from a state where oil is ejected to burn using only the middle combustion nozzle 2 (70% combustion), a low combustion electromagnetic valve 1A is fully opened, and the electromagnetic valve 2A is fully closed after the passage of a predetermined time during which the ignition to the nozzle 1 becomes positive, thus oil being ejected to burn using only the nozzle 1 (30% combustion). Further, when the load is increased from the state (70% combustion) where oil is ejected to burn using only the middle combustion nozzle 2, the electromagnetic valve 1A is fully opened, and oil is ejected to burn using both nozzle 1 and 2 (100% combustion).

Title: Electromagnetic ultrasonic measuring device
Inventor: YAMAGUCHI HISAO
IPC: G01N29/04
Filed: 1983-03-30
Abstract: PURPOSE:To reduce a blind zone by stopping the charging of the capacitor of a transmitting circuit until the ending point of an ultrasonic-wave measurement period. CONSTITUTION:A DC coil 2 is excited by a DC power source 6 to apply a DC magnetic field to a material 1 to be checked. While the capacitor C is charged, a timing control circuit TI generates a synchronizing pulse to supply the wide gate pulse to a thyristor SCR through a gate control circuit GA. Then, a charge from the capacitor C flows in the order of C, SCR, transmitting coil 4, diode D2, and C and its inverted current flows in the order of C, diode D1, transmitting coil 4, SCR, and C. The varying magnetic field of the transmitting coil generates varying strain in the material 1 to be checked and the voltage developed across a receiving coil 5 is detected through an amplifier 8 and a signal processing circuit 9. When the thyristor SCR is turned off by the pulse from the gate control circuit GA, the capacitor C is charged until the timing circuit TI generates the synchronizing pulse to reduce the blind zone.

Abstract: PURPOSE:To prevent shortage of oil of oil-lubricated bearings, by feeding lubricating oil to the bearings via an oil supply passage prior to starting rotation of a main shaft in restarting operation of a vertical shaft type rotary machine after it is kept at rest for a long time. CONSTITUTION:When operation starting instruction is given, a switch 18 is closed since the level of oil in a chamber 9 of an oil tank 6 is at its upper limit and a float 17 is also raised to an upper position. Resultantly, a solenoid valve 16 is opened for feeding oil from the chamber 9 to bearings 3, 4 via an oil feed pipe 11 of an oil feeding circuit. The oil thus supplied to the bearings 3, 4 flows downward to a bearing 5 and then to a lower oil tank 12. A predetermined time later after feeding oil to the bearings 3, 4, a main shaft 2 is set into rotation and a screw pump 13 disposed in the tank 12 is driven along with rotation of the main shaft 2, so that oil in the tank 12 is returned to the chamber 9 in the tank 6 via a return pipe 14.

A crush pipe 20 is fixed to the lower cover 14, and a cover 22 is supported to the free end of the crush pipe 20. At the time of an accident, the crush pipe 20 is therefore deformed plastically, and energy is reduced to zero on one side, while additional decelerating stroke is generated on the other side. Load applied to a knee is therefore reduced, and an occupant can be protected regardless of his/her weight.
